Description

Technical Field

[0001] The utility model relates to the technical field of pipe connectors, in particular to a multi-interface elbow pipe fitting. Background Art

[0002] Pipe fittings are widely used in the connection of gas and liquid transmission pipelines. Commonly used pipe fittings include two-way joints, three-way joints, four-way joints, 90° elbows, 45° elbows, etc. The 90° elbow pipe fitting is one of the commonly used pipe fittings because it can connect two pipes that are perpendicular to each other. Pipe fittings are widely used due to their simple production and low cost. At present, most gas and liquid transmission pipelines are equipped with various instruments, such as pressure gauges, flow meters, thermometers, bypass lines, etc., which requires multiple three-way and four-way joints on the transmission pipeline. If the pipeline needs to be reversed, a 90-degree elbow must be connected, resulting in many joints on the entire transmission pipeline. Not only is on-site installation troublesome and wastes winding tape, but there are many connection points, which can easily cause water leakage problems in the later stage. Utility Model Content

[0003] In order to solve the above problems, the utility model provides a multi-interface elbow pipe fitting, which can simplify the difficulty of pipeline installation and save installation materials.

[0009] On the basis of the above scheme and as a preferred scheme of the above scheme: a threaded structure is provided on the inner wall of the external thread cover of the external thread sealing plug, which covers the external thread interface, and the two are threadedly matched; the external thread sealing column of the external thread sealing plug is an inverted cone structure, which is inserted into the external thread interface, and the two are tightly matched.

Several pipe interfaces are set on the first main section, and the pipe interfaces are facing the upper side, front side or lower side, which is convenient for installing various instruments, valves and bypass pipes, etc., simplifies the installation of components, reduces leakage points, and extends the service life of the pipeline.

[0012] 2. The pipeline interface can be set to an internal thread interface or an external thread interface according to needs. The pipeline interface can be idle. The idle pipeline interface can be installed with a sealing plug for sealing, which does not affect the normal use of the pipeline. When a bypass is added later, there is no need to cut the pipeline to install a tee. You can directly select the idle pipeline interface in the appropriate position. It is convenient and quick to use. BRIEF DESCRIPTION OF THE DRAWINGS
